Full Stack JAVA Web Application Development

Many organizations need  web application development for business reasons. The technical requirement requires some one with full stack development expertise. However such expertise is difficult to get and if available costs are prohibitive. In  North  America  there is a shortage of full stack java development expertise.

 

 keencomputer Solutions provide full stack java development for small and large organization to fill the  skill gap. We provide  contract software development at an attractive price point.

 

Full stack Java development   relates to web application development that is hosted on  cloud platforms such and google cloud and or DigitalOcean[3]. Development of such web application requires understanding of complex technology stack and this is where main problem arises[4].

 Much of the technology stack is not taught at University courses and developer has to learn it on the job and or through specialized courses that is taught online.

 

Most web application is three  tire; front end- middle tire and back end

The front tier call for  knowledge of the following technology:

1.0 HTML/CSS and libraries such as twitter bootstrap

2.0 JavaScript and Libraries such as Angular and Reduce and Redux and View[1]

 

 The middle tire needs the following

 

1.0 Business Logic and framework such as spring boot and spring  MVC[2] frameworks

 Typically languages like java, php and ruby on rails MVC is used in middle tire

 

 Some times in memory database such as memcache[3] is used here to improve performance

 

In the end tire, We need the following:

RDBMS such as Postgres and Oracle
Many times NOSQL Database are used such as MONGODB
is used for BIG Data applications. NO SQL Database are used in Conjunction with Data mining and Predicative Artificial Intelligence and Machine Learning.[3]

Operational Management of the web Application is managed by devops[4]. The Agile Design and specification capture is
generally managed using Behavioral Driven design process.[5]

 

Distributed Applications

 

Most Full tack Java applications are Distrusted in Nature. REST API  is used to communicate such Services. The above mentioned three  tier application is also made distributed  some times using Docker Micro Service Architecture[6].

When implemented effectively, Continuous Delivery (CD) embraces the DevOps philosophy of collaboration between traditionally separate teams: development and operations. CD is the automated implementation of the build, deploy, test, and release process. With CD, software is always in a releasable state. With every change to any part of the software system — infrastructure, application code, configuration, or data — a release candidate goes through a delivery pipeline where the software is created, environments are built, databases are constructed, tests are run, and software is deployed. Many tools make up a platform capable of moving the software system along this pipeline.

Efficient Software Development

 

Many small and medium sized companies need software development done inhouse. However, there are couple of problems.

 

1.0 Fresh Community College and University graduates are not well prepared to apply the knowledge of academic learning to software development.

2.0 The academic and industrial gap of software development is generally learnt on the job and on one’s own initiative. The training takes about 3-5 years.

3.0 Many small and medium business unknowingly becomes the training ground for fresh graduates. The fresh graduates learn the trade at your expanse and after some time they go to a better paying company, leaving you cold

 

So what is the solution?

 

1.0 Keen computer was established to exactly solve this problem. We are well trained in contract software development. We bring our expertise to be productive in first hour- not first year. And we are economical. You can expect to pay 50% of the cost of in-house development cost.

 

2.0 We achieve this level of efficiency by using process and methods that is industry standard and proven to be effective in software development. Software architecture using industry standard UML- 2.0 is an example of this process. Many small business lacks the knowledge of best practice of software development and in the process wastes time and money unnecessarily.

 

3.0 We continuously communicate the project and progress with your in-house employees and management using continues delivery method. DEVOPS is one such popular method.

 

How we bring value to your company. Here are some salient points:

Snort Network intrusion Detection System

Snort is a free and open source network intrusion prevention system (NIPS)[citation needed] and network intrusion detection system (NIDS)

Snort's open source network-based intrusion detection system (NIDS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching. These basic services have many purposes including application-aware triggered quality of service, to de-prioritize bulk traffic when latency-sensitive applications are in use.

The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, common gateway interface, buffer overflows, server message block probes, and stealth port scans.[10]

Snort can be configured in three main modes: sniffer, packet logger, and network intrusion detection.[11] In sniffer mode, the program will read network packets and display them on the console. In packet logger mode, the program will log packets to the disk. In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. The program will then perform a specific action based on what has been identified.

 

 Please contact us to learn how SNORT can help your network Management  and security solutions.

 If your organization uses multiple spreadsheets across organization for information storage and reporting, you need to consider a  database  for efficiency and productivity.

 

Microsoft Access is a database management system (DBMS) from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.

Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.[1]

Software developers, data architects and power users can use Microsoft Access to develop application software. Like other Microsoft Office applications, Access is supported by Visual Basic for Applications (VBA), an object-based programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating system operations.
